Qualcomm’s Adreno 330 GPU will be replaced by new Adreno 400-series parts and naturally the new generation will be faster than the one that sits inside the Snapdragon 800.

Our sources are telling us that Adreno 400 is expected with the new version of Snapdragon that is set to debut in early 2014. Traditionally Qualcomm uses CES to showcase its new chips and CES 2014 starts on January 7th, so it sounds like the right time for it.

The only key detail that we learned about Adreno 400 is that despite a significant increase in GPU performance the chip won't have a compute part and it doesn’t support OpenCL. Many will see this as a handicap, but to be honest we see limited uses for OpenCL in mobile chips, at least for now.

Nvidia's Logan comes with Open CL 1.1 as well as Open GL 4.4 support. Adreno 330 can push 3.6 Gigapixels a second making it one of the fastest GPUs in mobile market, capable of going head to head with the Tegra 4. Adreno 400 naturally ends up faster.

Then again we expect that Logan Tegra 5 has what it takes to dominate the mobile GPU market in 2014. Let’s not forget about PowerVR 6-series parts, ARM’s recently announced Mali 700-series or Vivante’s upcoming mobile GPU designs, either.

Unlike the AMD-Nvidia duopoly in the PC GPU market, right now there are five players vying for the top spot in the mobile space and things are bound to get interesting.
